RICHARD E. JONES, OF HAGERSTOWN, MARYLAND.

FASTENER- Application filed April 14, 1919. Serial No.

To all whom it may concern:

Be it known that I, RICHARD E. JONES, a citizen of the United States, residing at- Hagerstown, in the county of Washington and the State of Maryland, have invented certain new and useful Improvements in Fasteners, of which the following is a specification.

This invention relates to fasteners espe cially designed for use in connection with large refrigerator and cold-storage room' doors. It may however be used in connection with any door requiring a fastener of this type. It is designed to be automatically locked by spring pressure on closure of the door, and is provided with means whereby it may be unlocked from the inside, thereby avoiding all danger of an employee being exposed to the danger of being confined in a cold storage vault, ice house or other place Where it would be dangerous to health and life to remain for several hours.

The invention consists in the novel features of construction hereinafter described, pointed out in the claim, and shown in the accompanying drawings, in which Figure 1 is a face View of the fastener applied.

Fig. Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 1.

In these drawings 1 designates a door, and 2 the wall of the inclosure to which said door is applied.

My fastener comprises a casting 3 having at one end a housing 4 within which is pivoted an end of a latch 5. At its free end the latch carries a roller 6, shown in dotted lines in Fig. 1. This roller engages a suitable keeper 7.

A bifurcated bracket 8 carried by the casting 3 forms a bearing and pivotal point for the lower end portion of a releasing lever 9, the said lever having a nose 10 that engages a slot 11 in the latch 5. The lever, above the pivotal point, is provided with a slot 12.

A push rod 13 works through the door,

and may be packed if desired in any suitable 2 is a section on the line 22 of copies of this patent may be obtained for five cents each, by addressing the Specification of Letters Patent.

manner, and the outer end of this rod carries a bifurcated member 141- which straddles the lever. A bolt 15 passes through this member and through the slot 12. A push handle of any type, as at 16 is secured to the inner end of the rod.

A bracket 17 is arranged vertically on the door and the latch 5 works vertically within said bracket.

The upper portion of the bracket is in the form of a downwardly open housing 18. A coil spring 19 is arranged in the housing and bears at its upper end on the top of the bracket and at its lower end on the latch 5. It is held in position by a pin 20 carried by the latch and which extends through the spring and upwardly through a suitable opening in the upper portion of the bracket. This spring forces the latch downwardly and automatically throws it into locking position when the door is closed.

The fastener is released by lifting the latch vertically against the pressure of the spring, either by pulling outwardly 011 the lever 9 or pushing from the inside on the rod 13.

What I claim is:

A fastener of the kind described comprising a casting secured to the outer face of a door, a latch pivotally mounted thereon, a roller in the free end of the latch, a keeper adapted to be engaged by the roller, a vertically arranged bracket spanning the latch, a
